1. A method of making a porous nanocomposite, the method comprising:
at least partially immersing a porous polyurethane scaffold structure in an aqueous solution to saturate the porous scaffold structure with the aqueous solution, the aqueous solution comprising one or more metal salts, metal acids, or mixtures thereof; and
heating the porous scaffold structure while saturated with the aqueous solution to form and deposit, by evaporation of the aqueous solution and without adding a reducing agent, a plurality of metal nanomaterials on the porous scaffold structure from the one or more metal salts, metal acids, or mixtures thereof as the porous nanocomposite, the metal nanomaterials comprising iron, copper, aluminum, nickel, zinc and/or titanium nanomaterials, wherein each of the plurality of metallic nanomaterials is directly bound to the polyurethane porous scaffold structure of the porous nanocomposite.
